Summary
Dialectical Behavior Therapy (DBT) is an effective treatment for eating disorders, showing promising remission rates for Binge Eating Disorder (BED) in both standard and guided self-help formats. Traditional guided self-help models typically combine weekly chapter readings with a limited number of brief therapist meetings. However, the requirement of weekly book readings can be particularly challenging for individuals with BED, who often exhibit impulsive personality traits, psychiatric comorbidities, and weight-related health problems. This study was developed to test a version of guided self-help DBT-BED delivered through video lessons instead of text. This randomized clinical trial will be conducted at the Eating Disorders Program of the Institute of Psychiatry, Hospital das Clínicas, Faculty of Medicine, University of São Paulo (AMBULIM IPq HC FMUSP), Brazil. Eighty adults with BED will be randomized to either an experimental group (weekly video lessons) or a control group (weekly text-based readings). Both groups will undergo a 13-week intervention, including six brief 30-minute online guidance sessions with a psychologist. The primary outcome will be full remission from binge eating episodes at the end of treatment and at the 3-month follow-up. Secondary outcomes will include changes in eating disorder psychopathology, emotion regulation, quality of life, self-esteem, and dropout rates. Statistical analyses will follow the intention-to-treat principle.
